To all, whom, it may concern.-

Be it known that we, CHARLES H. PALMER and JOHN W. DENMEAD, of Akron, inthe county of Summit, and in the State of Ohio, have invented certainnew and useful Improvements in Printing-Presses; and we do ereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, in which- Figure 1 isa side elevation of a multicolorprinting press embodying our invention.

ig. 2 is an end elevation thereof. Fig. 3 is a detail View, in sideelevation, on a larger scale, of one of the form-cylinder mechanisms;and Fig. 4 is a detail view in section ofone of the form-cylinderbearings.

Letters of like name and kind parts in each of the figures.

The object of our invention is to provide a printing-press of suchconstruction as to greatly facilitate the work of assembling its parts,to enable the forms to be moved rela tive to the impressionecylinder forboth avoiding printing on the blankets andqiermitting adjustment foraccurate register, and to enable the inking-rolls to be lifted from theforms to avoid injury to the inking-rolls when they are not in use andto these ends our invention consists in the printing-press having thefeatures of construction substantially as hereinafter set forth.

We illustrate our invention as embodied in a color-printing press ofusual general construction that is. it comprises a frame A, animpression-cylinder B, and a series of form-cylinders O and C, groupedaround said cylinder. The frame A com rises a base and two side piecesthat are bolted to the refer to like base, and in each side pieceis abox or bearing D for the shaft E, on which the impression-cylinder B ismounted. Each frame side is fori'ned of two parts that are joined on ahorizontal plane passing just above the bearings of the shaft E, eachshaftbearing D being placed in a cavity in the upper art of the lowersection of the frame side, w ch is covered by the bottom of .the uppersection of the frame side. It will be apparent that with thisconstruction of frame the Work of assembling is rendered very convenientand easy, because the work of mountingthe large impression-cylinder canbe done without the hindrance that would be occasioned by the necessarypresence of the upper side section were it an integral part of the lowersection. To give as com lete access as 0881- ble to the parts inside theframe, the ame sides are, as shown, of open-work construction.

For driving the impression-cylinder it has 'a large gear F, that mesheswith a gear G on a driving-shaft H.

For each form-cylinder there is a shaft I, and upon the latter is a gearJ, that meshes with and receives motion from the impression-cylindergear K. Said shaft I is ournaled at opposite ends in boxes L and L, thatare respectively mounted in openings in arms or brackets a and a on thetwo frame sides, which openings in a direction radial to theimpression-cylinder axis arelonger than the boxes, so that there may bebodily movement of the form-cylinder to and from the imression-cylinder. The form-cylinder is he (1 yieldingly at the innerlimit of its motion by means of a spring M, interposed be- .tween theouter end of each box and a screw a. At its inner end the box is engagedbyv the ends of two screws 0 and O, that fix its inward movement. Twoscrews 0 and O are provided for each box, so that should it be necessaryto move the cylinder outward-as, for example, to disengage thecylinder-gear from the gear F to free that cylinder for adjustment forsecuring perfect registersuch can be done Without its being required toagain adjust it, one screwin such case being used'to force the boxoutward and the other being undisturbed, so that on the return of thecylinder to its inward position the undisturbed screw will arrest it atthe same place it previously occupied.

J ournaled on a round projection Z on each box L concentric with thecylinder-shaft is a rocking plate P, that has a peripheral camsurfaoe p,which engages a projection or roller Q on the side of the box bracket eand which when moved in one direction acts to move the box andcylindcroutward against the pressure of the spring and when moved in theopposite direction permits the spring to act to restore the formerposition of the parts. The outward movement of the cylinder by action ofthe cam is not sull'icient to disengage the gears J and K, but is onlysufl cient to prevent rinting by the cylinder, and is provided to 0sviate printing on the blanlrets when no paper is run through the press.

For rocking the cam p'late I it has an arm ,1), and to enable all of thegroups of formcylinders to, be simultaneously operated the series ofarms on the same side of the press are connected to ether by links R andR and the end one of t is series on one side is connected by a link S toan operating-lever T, that is secured to a shaft U, mounted in bearingson the frame sides and extending across the press from side to side. Thefamiliar device of a notched segment and dog is provided for locking thelever at each limit of its swing to secure the form-cylinders in one orthe other of their positions, It will be understood that the cam-platesand the link colinections are on both sides of the press and that theseries of cams on the side that does not have/the operating-lever isconnected to the shaft U, so that both series may be operated by the onelever.

For each form-cylinder there is an'inlr-fo'untain V of commonconstruction, from which ink is taken and transferred to the form by aseries of rolls. The main distributing-roll W of each inking apparatusis fixedly mounted in hearings on extensions or brackets on the framesides; but the other rolls X and X are iournaled in a frame Y, that ishin ed at one extremity by a pivot Z, so that tie frame, with saidrolls, may be swung outward on the pivot away from the main distributingroll and the lorm-cylinder. Attached pivotally to the free extremity ofthe frame Y is pne end of a bar or link A, whose other end has a pin orstud a which en ages a notch or ooen ended slot in the cam-p ate P,'sothat by the rocking of the latter the roll-carrying i'ralne may bemoved. When the cam is rocked to shift the cylinder from contact withthe im ressioncylinder, the inking rolls are simu taneously lifted fromthe form'- cylinder, and on the return of the form-cylinder to printingposition the inking-rolls are restored to contact with theform-cylinder. It will thus be seen, too, that the singleoperating-lever controls the movements of both all of the form-cylindersand all of the movable inking-rolls. Should it be desired to move theinking-rolls independently of the movement of the form-cylinders, thiscan be done by reason of the pin-and-slot form of connection between thebars A and A and the cam-plates P and P. A-rod B connects the two framesY and Y of the same mechan- ISIIl. I

By mounting the inking-r0lls X and X in movable frames the rolls whichhave contact with the form-cylinders can be lifted out of from restingon the irregular type-surfaces obviated. The supply of ink to the mamdistributing and the form cylinders is stopped when the latter are notprinting, and access I to said cylinders for cleaning or other purposescan be readily load without disturbance of the working position of theinking-rolls in their bearings. .i

The doctor-roll D is vibrated by a cam E on the form-cylinder shaft,which acts on a roll F on a yoke G, that is connected with the doctorroll-carrying frame H Having thus described our invention, what we claimis l 1.
